To aZZ whom it may concern Be it known that I, AUeUsT RIEBE, engineer, asubject of the King of Prussia, German. Emperor, residing in Berlin, N.W., Huttenstrasse 34-35, in the Kingdom of Prussia, Germany, haveinvented certain new and useful Improvements in or Connected withPartition Devices for Ball-Bearings, of which which'the following is afull, clear, and exact description.

The s ring-acting-intermediate pieces between tffe balls which have comeinto such general use in connection with ball-bearings ave oftenexcessive demands made upon them in conse uence of the accelerativepower imparted to t e balls and the compression togetherof the latterthereby caused, the resu t of which is the increased wear and tear andultimate destruction of the springs, as well as of the end plates, whichin the case of the partition device selected as an illustration of thepresent invention form a closure for the springs at both ends, thuseriling the precise action of the bearing. order to overcome this eviland for the purpose of regulating the admissible compressibility of thespring insertions or partition devices, a laterally-expansible sleeve dis, according to thepresent invention,.fitted onto, so as to more orless embrace, the springs of the said insertions, the sleeve in questionbeing open laterally with aspring action in a tangential direction andst ff in an axial direction, whereby compression, beyond a certainpoint, of the spring parts of the partition devices brought into actioncan be avoided. For instance, in the device selected for illustrationthe balls," even when the partition deviceis fully compressed, areable'to issue. from their recesses in the end plates. In the latter 1case the compressibility of the spring-acting partition devlce thatis,the length of sleeve dmust be so regulated that the play allowed V forspring action shall be less than thedepth of the recesses e in the endplates 6, becauseif the play should exceed the depth ofjthe' recesses ein the end plates theballs would, in the case of an overcompressedintermediate piece, of themselves come out of their respective recesses,and so considerably interfere h' rking 1 In the accompanying drawingsthe invention is illustrated, by way of example, in contion device orintermediate piece consisting of,

one of the end plates in elevation. Fig. 2 is a is an end elevation ofanother style of sleeve; Fig. 4 is a cross-section showing a third styleof sleeve. Fig. 5 is a side elevation with the rings partly broken away,illustrating the parts assembled in a bearing.

The device shown in Fig. 3 is desi ned for tions require the spring 0 tobe completely encases the latter must, as shown, be made in two parts dand d overlapping each other and supporting over their entire endsurfaces the two end plates 1) when the spring acting partition devicesare in a compressed osition.

a modification 0- the device hereinbefore described. As hereinbeforementioned, the sleeve d must in order to be pressed over the sizeapproximating the diameter .of said spring; but, owing to this notch orsl1t;m

no continuous support for the end plates. In fact, the plates aredeprived of support in the part where the slit or openin comes, so thatin certain positions of the evice the end opposite corners of the sleeved forming the t1 ting or tipping axis. This risk of tipping is of coursemereased by the point of contact of the ball not being in the center oftheend plate,- but situated eccentricallywith relatlon to the same. r

, When the-position'of the partition device .is 'suchthatthe point ofcontact of the ball A reaches itsnearest position to the tilting axis,this point of contact may under given conditions be soclose to thetipping or tilting edge that the sleeve (Z is not able at this polnt tothe utility o the sleeve (2 itself is-also renthis d' culty, it has beenfound that the best construction for the sleeves is that illustrated inFig. 4, in which the sleeve d, in contrast to the previous form ofconstruction, is extend- 1231611 a way-as to orm two extensions (Z, "W

I What I claim as my invention, and desire tosecure by Letters Patent, is

3. In partition devices for ball-bearings a spring, a pair of endplates, and a sleeve (Z adapted to be introduced laterally over thespring and having extensions (1 to providebearings for the end platesbeyond the openin in the sleeve.

in witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
